Leave the Pennsylvania Station 'bout a quarter to four
Read a magazine and then you're in Baltimore
Dinner at the diner, nothing could be finer
Than to have your ham and eggs in Carolina

This promised timeline has been bothering me ever since April, when I took a trip on this very route, Penn Station to 'Carolina'. A Harper's or something similarly dense might occupy you from New York to Baltimore, but your ham-and-egg dinner would take place in the middle of the night. But maybe there are two trips to the dining car, with ham and eggs being breakfast the next day? It is kind of an odd dinner.
